In all cases the cause can be either a STD or a non-STD
infection. If you have been sexually active, then it is important to test for STDs,
bacterial vaginosis and fungal infection. Non-STD infections can be either bacterial or fungal.
Emperically (or without testing), usually a combination of antifungal and antibacterial cream is tried. This usually involves metronidazole with either of these antifungals: Clotrimazole 1%, Miconazole nitrate 2%, Tolnaftate 1% and Butenafine hydrochloride 1%.
